APPAaATnsmDIcATmG AVERAGE SPEED F012. EHICLES.

Application filed October 29, 1926, Serial no. 145,03 and in Spain Aprfl-24, 1926.

The drivers of motorcars and of vehicles in general have always been interested in knowing, not only the speed attained-at any given momentfbut also the averagespee d obtained over a'certain distance. This has M 1 points of the plane,' to 'eaeh of which will corhitherto been obtained, by dividing the distance' covered by the time spent in covering the same, an operation" that, in'addition to be.- ing troublesome, frequently'gives i ise tjo' er rors. The errors that may befca'used these apparatuses, even when they answer "ng in conditions that compare unfavourably what is ordinarily required of them, are'not such as to appreciably aflectthe result',l and the total absence o f -any speed-indicating mechanism, which is always liableto errors, is worthy of note. v

The object of the inventionisto provide improved apparatus Ywhichfshows eo tinu: ously by means of a marker runni'n g along a graduated limb the average .speed corresponding to the distance; covered froma given point or instant and which apparatus saves work and at'the same time attains the precision peculiarto a machine basedontw'o mechanisms that are recognized'to exact, that is to say chropometer an'd a lmileage recorder. i

With the above and other objects'in View, my invention consists in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings H Figure 1 is a diagram of a graph for use iii-connection with my improved apparatus.

Figure 2 is an elevation ofniy improved apparatus. A 1

Figure 3 is a similar view at right angles to Figure 2.

Figure 4 is a detail elevation partly in section showing the needle, the stylet and coacting devices.

Figure 5 is a detail elevation of the segmental limb N with which the stud M coopcrates.

The end of a stylet E moves in a plane, simultaneously in two directions, which give the corresponding resultant; these directions are parallel to two coordinate axes situated in the said plane, the origin of which axes may be called 0 (see Figure 1).

The distances covered by the stylet,- parallel to an axis T, are proportional to the time, and the distances parallel to the other axis D, are proportional to the distances covered in kilometres. In practice this proportionahty s secured by meansof a mechanism simllar' to a time measuring apparatus and of a kllometer recorder'or other like mechanism.

Thus the stylet will pass over the different respond ,a space traversed and a time spent n traversing 1t, and thereby an average.

It will be seen that', if the stylet starts from I the point 0, the points of like average will correspond to straight lines forming a sheaf and all concurrent 'at the origin O.

" "Thus, a needle rotating round an axis projected at the origin 0 and constantly following the stylet, will in succession coincide with the straight linesforming thesheaf and, if at the intersection of the circle traced by the end ofthe needle and the straight lines of the sheaf,. we place the numbers correspondingto the averages, the'needle will always be sought; Y I I V In Figure l 'are shown the'axes T'and D formingfan' angle'gie'aterfth'an 90 degrees, and thestraight lines of IikeJaverage, which have been traced on'the figure on the' supposition thata minute and a kilometre are-represented by the same measurement 'on the respective axes. The graph is adequate for a distance 015.300 kilometres and a "time of 5 hours as a maximum run,

Detailed description of the apparatus.

I The two axes of times and spaces covered are given material shape in'the form of the parts B and .D' (Figure .They might form any angle, but the angle shown on the drawing is the mostsuitable. I I

Part B (Figures 2 and 3) is a rack, with which the wheel K (Figure 3) forming part of the clockwork apparatus A (Figures 2 and 3) engages; by the rotation of the wheel the apparatus A moves along the part B.

Matters are so arranged that by bringing A to the top of B, the clockwork is wound up; thereby the spring is able to move A to the bottom of B in a suitable space of time.

B at the bottom carries a sleeve C (Figure 2) threaded internally, and through the inside of this sleeve passes an axis D (Fig ure 2), fitted with the corresponding screw. By the rotation of D, B is made to move in the required direction as it is prevented from rotating by the guide-pieces G (Figures 2 and 3).

Rotation is communicated to D by the axis on the number showing the'aver age that is portiomrl to the space traversed by the ehrele.
